Matter protocol

matter Is a general application layer specification .

matter There are currently two branches ,matter over Thread and matter over Wi-Fi. among Thread It is a kind of short distance designed specifically for the Internet of things 、 low power consumption 、 Support IPv6 Of Wireless mesh network networking protocol . To achieve the goal of interoperability architecture between devices ,Matter Specification equipment and controllers （ be based on IPv6 Network of （Thread or Wi-Fi）） Application layer .

 

 

The application layer can be further subdivided into seven main components ：

1. application ： High level business logic of the device . for example , Applications that focus on lighting may include processing open / Logic to turn off the bulb and its color characteristics .
2. Data model ： Data primitives that help describe various functions of the device . When intentionally interacting with a device , The application operates on these data structures .
3. Interaction model ： Represents a set of operations that can be performed on a device to interact with it . for example , Reading or writing attributes on the device will correspond to the interaction with the device . These operations operate on the structure defined by the data model .
4. Action frame ： Once an action is built using the interaction model , It will be constructed into a standard packaged binary format , In order to be in “ line ” Get a good expression on .
5. Security ： Then the encoded action frame is sent to the security layer to encrypt and sign the payload , To ensure that both the sender and receiver of the data packet protect and verify the data .
6. Message frames and routing ： Through the interaction of encryption and signature , The message layer builds payload formats with required and optional header fields ; It specifies the properties of the message and some routing information .
7. IP Framing and transmission management ： After building the final payload , Send it to the underlying transport protocol for data transmission IP management .

Matter SDK

 Matter SDK （https://github.com/project-chip/connectedhomeip） Is a Matter Standard open source code base , At present, it is still actively developing .
